ⓘ Corpus allatum

In insect physiology, the corpus allatum is an endocrine gland which generates juvenile hormone, as such, it plays a crucial role in metamorphosis. Surgical removal of the corpora allata can cause an immature larva to pupate at its next molt, resulting in a miniature adult. Similarly, transplantation of corpora allata from a young larva to a fully mature larva can greatly extend the larval stage, resulting in an equivalent to gigantism.

In many Diptera species, the corpus allatum is fused with the Corpus cardiacum, forming a "ring gland", also known as Weismanns ring.

In Lepidoptera species, the corpus allatum acts as a venue to free for prothoracicotropic hormone which is produced by the brain.
